I am horrible at math. Any good websites that might have some calculators that can help me. I really only know the basics.
Its not my math homework first off people. I dont' go to school. I will have you ALL know that my life hasn't been the easiest and thanks to my parents I missed ALOT of school and because of that I have suffered ALOT with math. I've missed months of school year by year. Not because of my choice because I was moved around from home to home to home. So don't you dear come at me. To you this may be very easy but to me its really hard. Okay so don't get an attitude. You all can either help me out. OR you can SHUT UP and leave your RUDE COMMENTS to yourself. Thanks alot.
